No. I wanted to specify the author, but I'm having trouble figuring out how to represent it. See:

Yes. Everything in <Point> is straight from GML 3.3. And the double-nesting will be useful. For one, it will avoid the problem with <description> above, where you don't want to mix CDATA with an element. I.e. it's easy to slip an <author> element in as a child of <point> without messing with the location specification in <Point>.

Why the <posList> element? I'm not sure, but greater GML minds than mine chose that as the most compact encoding, so there must be a good reason.

I also realize that having srsName on <point> is now illegal in the data model, so it's moved to <Point>

Thanks. That's a good enhancement. I've updated it in:
